BREAK­ING DOWN THE KTM SIZ­ING

Dirt Rider - - Comparison -

Here is a quick re­fresher of what each KTM en­gine and chas­sis char­ac­ter is like from when we tested them ear­lier in the year.

250 SX-F: The 250 SX-F doesn’t have a big bot­tom-end hit but churns out mid- to top-end horse­power like no other 250 in the class. You can’t lug it as much as other 250s, but if you are a screamer and like to get the most out of each gear, this might be the right en­gine char­ac­ter for you. The chas­sis is light and nim­ble and is a very ca­pa­ble cor­ner­ing ma­chine. The fork can get a lit­tle soft at times for a heav­ier rider, but over­all bal­ance of the KTM 250 SX-F is com­fort­able and plush.

350 SX-F: More torque than a 250 SX-F out of cor­ners, but the 350 pulls sim­i­larly to the 250 in the mid- to top-end power. The 350 can be lugged a lit­tle more than the 250 yet still prefers to be revved out like the 250. The chas­sis is still very 250-es­que feel­ing and can be flicked around just like its lit­tle brother. The fork, how­ever, is not quite as com­fort­able through the mid-stroke like the 250 and 450 and can be some­what hard to dial in at cer­tain tracks when there are big­ger brak­ing bumps. Vi­bra­tion is not an is­sue when the en­gine is spooled up.

450 SX-F: The Big Bertha of this group feels su­per light com­pared to other 450s in its class. The en­gine char­ac­ter is smooth off the bot­tom, but you are able to carry sec­ond gear longer on this 450 than all other com­peti­tors in its class. Mid- to top-end is more than you will need but will never rip your arms out of their sock­ets while in­creas­ing the throt­tle. The WP sus­pen­sion has enough move­ment and hold-up for an ag­gres­sive rider but is also stiff enough for a slower rider who may not be able to clear all of the ob­sta­cles on the track.
